Alpha levels help in GM7 PRO

So I have this script right;

and like, it doesn't work.
In case you can't tell I'm trying to make obj_gradient1 to get less transparent the closer you are to it. Probably doing this really wrong, kind of a novice here!
Help is appreciated!

Making it less transparent the closer you are to it?

Here's some Pseudo-Code:
Set Alpha to (MaximumDistance-Distance)/MaximumDistance

Actually, I have to check something about Game Maker, so that Division may change a little bit.

EDIT: Alright, the code should be good. I wasn't sure whether GM uses 255 or 1 for Completely Opaque.

I'm using your code but it's kind of confusing me... I now have it set to;

I also tried it replacing 500 with distance_to_object(obj_player), but that didn't work either.

I also tried it replacing 500 with distance_to_object(obj_player), but that didn't work either.

maxdist = 500; // This Variable tells the distance at which the Gradient will be fully invisible. If the Player is any farther than this, it will also be invisible.
obj_gradient1.image_alpha = (maxdist-distance_to_object(obj_player))/maxdist;
That will make sure it is not set to more than one.

Also, when you say it "doesn't work", do you mean the Gradient stays invisible, or fully visible?

BTW, if you take a class like Physics or Chemistry, this is a simple modification of the Percent Error Formula.

if image_alpha is 1 or greater, it will be fully visible
so image_alpha=0.5 will make the object half visible
irony: your original code made the object totally visible no matter what

hurr that's why I asked for help

but OniLink, your code worked with a bit of tweaking. Thanks dood.

You are very welcome!
